摘要:
An oxidizing antimicrobial treatment and products containing such treatment are described. The treatment involve, in part, preparing a substrate to accept an attachment of charged moieties, and a number of stabilized peroxide compounds on at least part of a surface of said substrate. When microbes, such as bacteria, having a net charge opposite to that of the charged moieties come in close proximity to the treated substrate surface, peroxide molecules from the substrate are activated and released to kill the microbes.
摘要:
A polymeric substrate primed with a treatment composition to allow better receptivity of an ink composition, and method for making the same, is generally disclosed. More specifically, the polymeric substrate can be a hydrophobic polymeric substrate such as comprising polyolefins, which exhibits better ink adhesion and rub resistance when pretreated with a treatment composition of the present invention.
摘要:
The present invention provides multicomponent fibers, nonwoven fabrics and surge management layers that include multicomponent fibers that comprise a first component that comprises a blend of a first polyolefin and from about 0.1 to about 5 weight percent of an ethoxylated hydrocarbon and a second component that comprises a blend of a second polyolefin and from about 0.1 to about 5 weight percent of an ethoxylated siloxane.
摘要:
A nonwoven material adapted for use as a surge layer or a transfer layer that includes a layer that includes fibers that have been treated with a polysaccharide, a modified polysaccharide, a derivative of a polysaccharide or a derivative of a modified polysaccharide is provided.
摘要:
A sorbent material is provided comprising a porous substrate, such as a nonwoven web, having a wetting chemistry distributed substantially throughout the substrate. The wetting chemistry can comprise (a) an aliphatic alcohol ethoxylate; (b) one or more of an alkyl sulfosuccinate, an alkyl sulfate and a sulfated fatty acid ester and, optionally, (c) a fatty acid ester ethoxylate. Various formulations are provided having low metal ion concentrations, anti-static properties and/or good absorption characteristics for a broad spectrum of liquids.
摘要:
An absorbent article includes a vapor permeable backsheet, a liquid permeable topsheet positioned in facing relation with the backsheet; and an absorbent body located between the backsheet and the topsheet. The absorbent body may include multiple zones of high air permeability. The absorbent article may also include a ventilation layer between the absorbent body and the backsheet and a surge management layer between the absorbent body and the topsheet. The article exhibits improved air exchange within the article during use. As a result, the article maintains the temperature and exhibits substantially reduced levels of hydration of the wearer's skin when in use which renders the skin less susceptible to the viability of microorganisms. The absorbent article may further include lotion formulations and/or treatment compositions thereon for maintaining or improving skin health.
摘要:
Odor reduction for products such as disposable diapers and training pants, sanitary napkins and tampons, incontinent products, and medical dressings is obtained by the use of an internal additive for synthetic polymers or an external additive for natural polymers. Results are further enhanced by the use of a surfactant especially in the case of synthetic polymers. Webs, fibers and films find uses as components of the described products and are effective in absorbing odors such as ammonia, triethylamine, indole and skatole, for example, which are commonly found in body fluids like sweat, menses, urine and fecal matter.
